Crystal takes over POC’s

Being able to breathe underwater has long been a fascination for mankind, but the bulky oxygen tanks and face masks take some of the romance out of it.underwater-v2

 

hey could soon no longer be needed however, thanks to the creation of the “Aquaman Crystal”, or to use its proper name, “[{(bpbp)Co2II(NO3)}2(NH2bdc)](NO3)2 * 2H2O”.

Just a spoonful of the crystal can absorb all the oxygen from a room.

The material is able to store the gas at a much higher concentration than oxygen tanks, meaning it would be far smaller and lighter to carry, and can slowly release oxygen when put under a small amount of heat.

Professor Christine McKenzie said the crystal could be valuable for lung cancer patients who must carry heavy tanks around with them, but “also divers may one day be able to leave the oxygen tanks at home and instead get oxygen from this material as it ‘filters’ and concentrates oxygen from surrounding air or water.”

“A few grains contain enough oxygen for one breath, and as the material can absorb oxygen from the water around the diver and supply the diver with it, the diver will not need to bring more than these few grains,” she added.

“When the substance is saturated with oxygen, it can be compared to an oxygen tank containing pure oxygen under pressure – the difference is that this material can hold three times as much oxygen.”

 

The “Aquaman Crystal” is sponge-like in consistency and uses cobalt bound in an organic molecule, getting its nickname from the DC comic book character that can swim underwater.

“Cobalt gives the new material precisely the molecular and electronic structure that enables it to absorb oxygen from its surroundings,” McKenzie said. “Small amounts of metals are essential for the absorption of oxygen, so actually it is not entirely surprising to see this effect in our new material.”

Scientists are now looking at whether the release of oxygen can be triggered by light, though at this stage the crystal is difficult to synthesize in large amounts due to its complex chemical formula.

Update: A representative for Syddansk University has issued a revised estimate of the compound’s efficiency. They told Vice in a statement: “I am just updating our story on our website, because it turns out that Prf McKenzie made a calculation error. Pls note that it is not a SPOONFUL of this stuff, that we need to rid a room of oxygen. It is a bucket (10 litres). We apologize.”

The material can however draw oxygen from water just as easily as from air, so it remains an interesting proposition for the future of underwater diving

COPD & why you should switch to Portable Oxygen Therapy

Many people with COPD need supplemental oxygen therapy. Unfortunately, some people who use portable oxygen are wary of travelling with oxygen. So they opt to stay at home instead of going out to see friends, shop, or enjoy a vacation.
But oxygen therapy can actually enhance your physical ability to go places and do things that the advance stage of COPD was keeping you from doing. Once you’ve learned what’s involved, you may find that oxygen gives you more freedom to go places and do things you want to do.
If you don’t use one already, you’ll need to switch to a portable oxygen delivery system for trips away from home. Portable oxygen concentrators (POCs), hold compressed oxygen in small tanks. Most POC tanks come with carrying cases and travel carts. These are excellent for using in airports or simply going sightseeing.
POCs run on batteries. Some batteries can last up to five hours. POCs also have AC/DC adapters so they can be plugged in when you are in a car or in a location with electrical outlets. The portable oxygen delivery system will allow you to have more freedom to live an active life.
Contact OxygenWorldwide – experts for over 20 years when travelling away from home. Our team of experts can help arrange all the necessary oxygen and POC’s during your holidays to help you and your loved ones have more freedom.

 

Oxygen and Travel – we have it covered

Travelling with oxygen has become much easier with the development of portable oxygen concentrators (POCs). These devices run on a battery pack, can be recharged, plugged into the wall or a cigarette lighter in a car, and can be taken on airplanes.

Oxygen-Users-Mall-Walkers

There are several makes and models, with widely differing features, so it is important to choose the one that is best for you, that delivers enough oxygen to keep your saturation 90 percent or greater at rest and with activity.

Some tips for air travel with POC’s:

·         Start making arrangements with the airline well ahead of time to find out which POC is allowed. Many airlines list accepted manufacturers and brands on their websites.

·         Allow plenty of extra time for check-in.

·         Carry several extra battery packs. FAA regulations require enough battery time to cover 150 percent of the flight time.

·         POC’s and battery packs can be rented.

·         Carry an extra three-way plug for recharging your POC in the airport. People often need to recharge their electronic equipment in the airport during layovers, and this will help assure that you will be able to recharge yours.

·         POC’s are exempt from the carry-on allowance.

·         Carry a prescription for oxygen, signed by your doctor.

Safe Oxygen Solutions

Medical oxygen adds a higher percentage of oxygen to the air a patient uses to breathe. And fire needs oxygen to burn and if a fire should start in an oxygen-enriched area, the material burning will burn more quickly.

When more oxygen is present, any fire that starts will burn hotter and faster than usual, it is crucial to follow safety precautions when medical oxygen is in use in a home.

Oxygen saturates fabric-covered furniture, clothing, hair and bedding, making it easier for a fire to start and spread, according to the regulator. Smoking is the leading heat source resulting in medical oxygen-related fires, injuries and deaths. Homes where medical oxygen is used need specific fire safety rules to protect people from fire and burns.

Simple, safety tips:

• There is no safe way to smoke in the home when oxygen is in use. Patients on oxygen should not smoke.
• Candles, matches, wood stoves and even sparking toys can be ignition sources and should not be used in the home.
• Keep oxygen cylinders at least five feet from heat sources, open flames or electrical devices.
• Body oil, hand lotion and items containing oil and grease can easily ignite. Keep oil and grease away from where oxygen is in use.
• Never use aerosol sprays containing combustible materials near the oxygen.
• Post “No Smoking” and “No Open Flames” signs in and outside the home to remind people not to smoke.
• Ensure smoke alarms are working by testing monthly. Daylight saving time weekends are great times to replace smoke alarm batteries. Also consider using 10-year batteries for smoke alarms.
• Practice a home fire escape plan with two ways out of every room at least twice a year.

Just a few grains of the newly synthesized material could allow us to stay underwater without scuba tanks

Using specially synthesized crystalline materials, scientists from the University of Southern Denmark have created a substance that is able to absorb and store oxygen in such high concentrations that just one bucketful is enough to remove all of the oxygen in a room. The substance is also able to release the stored oxygen in a controlled manner when it is needed, so just a few grains could replace the need for divers to carry bulky scuba tanks.

The key component of the new material is the element cobalt, which is bound in a specially designed organic molecule. In standard form – and depending on the available oxygen content, the ambient temperature, and the barometric pressure – the absorption of oxygen by the material from its surroundings may take anything from seconds to days.

“An important aspect of this new material is that it does not react irreversibly with oxygen – even though it absorbs oxygen in a so-called selective chemisorptive process,” said Professor Christine McKenzie from the University of Southern Denmark. “The material is both a sensor, and a container for oxygen – we can use it to bind, store, and transport oxygen – like a solid artificial hemoglobin.”

Varying the constituent structure of the material can also bind and release oxygen at different rates. This means it could be used to regulate oxygen supply in fuel cells or create devices like face masks that use layers of the material to provide pure oxygen to a person directly from the air, without the need of other equipment.

Even more interestingly, the material may also be configured in a device that could absorb oxygen directly from water and allow a diver to stay submerged for long periods of time, without the need for bulky air tanks.

“This could be valuable for lung patients who today must carry heavy oxygen tanks with them,” explains Professor McKenzie. “But also divers may one day be able to leave the oxygen tanks at home and instead get oxygen from this material as it ‘filters’ and concentrates oxygen from surrounding air or water. A few grains contain enough oxygen for one breath, and as the material can absorb oxygen from the water around the diver and supply the diver with it, the diver will not need to bring more than these few grains.”

Using x-ray diffraction techniques to peer inside the atomic arrangement of the material when it had been filled with oxygen, the scientists realized that once the oxygen has been absorbed it can be stored in the material until it is released by heating the material gently or subjecting it to a vacuum.

“We see release of oxygen when we heat up the material, and we have also seen it when we apply vacuum,” said Professor McKenzie. “We are now wondering if light can also be used as a trigger for the material to release oxygen – this has prospects in the growing field of artificial photosynthesis.”

There’s no word as yet on any possible commercial production or public availability of the material.

The research was published in the journal of the Royal Society of Chemistry, Chemical Science.
